Be it known that I, FRANoIs DANZENBAKER,

of Tashingtom in the District of Columbia, have invented a certain new and useful Improvement inBee-Smokers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in whichg Figure 1 is a Vertical section of one form of bee-smoker embodying my invention. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is a Vertical section of another form of smoker embodying` my invention. Fig. Li is a cross-section on the line 4: 4 of Fig. 3. Fig; 5 is a vertical section of another form of smoker embodying my invention. 'Fig. 6 is a horizontal section on the line 6 6 of Fig. 5; and Fig. 7 is a horizontal section of the smoker shown in Fig. 5, the air passagcs or fiues being situated on the interior of the fuel-box.

The object of my invention is to improve the construction of bee-smokers in the particulars of efficiency, so that an ample quantity of smoke shall be prodnced and fire maintained without difficulty, of durability, and comfortable handling; and to these and other ends, which will be hereinafter set forth, my invention consists in the bee-smoker having the features of construction substantially as hereinafter specified and claimed. v

My invention pertains to that class of beesmokers in which a cylindrical stove A and a bellows B are employed, the bellows being attached to the side of the stove, from which it is separated by a proper space. As is common, the stove and bellows are fastened together by plates C. Near its bottom the bellows has an air outlet or nozzle Z), from which the air under pressure passes into the stove at or near the lower end of the latter, and at its top the stove has a smoke outlet or nozzle a, pointing, of course, in a direction away from the bellows, and preferably in the form of a cone whose axis inclines slightly upward.

In all the forms of my invention illustrated the stove comprises an outer cylindrcal shell and an inner cylindrical shell D, the latter constituting a fuel or fire box.

In the form of my invention illustrated in Figs. 1 and 2 the inner shell I) rests at its lower end upon a grate E a short distance above the bottom of the stove, which grate consists, as shown, of a disk or plate having' numerous perforations, and said Shell D is sufficiently less in diameter than the outer shell as to leave an annular air-space between the two shells, longitudinal ribs or beads (Z being provided on the exterior of the inner shell D to touch the outer shell, and thus fiX the inner shell in a position concentric with the outer shell and preserve the annular airspace between them. The ribs or beads (Z may readily be formed by crimping or corrugating the sides of the shell, the latter being` easily and cheaply formed of sheet metal that is crimped and formed into a cylindrical Shape with its edges overlapped and suitably united, as by rivets or otherwise. In line with the bellows-nozzle Z) is a tube F, that enters the adjacent Wall of the outer shell of the stove through an opening in such wall that is situated with reference to the grate E so that a portion only of the air passing through such' opening` passes beneath the grate and a portion Will pass intothe stove at a point above the grate. The portion of the air that enters the stove at a point above the grate is directed upward between the two shells, for this purpose a Vertical longitudinal fiue G being provided, that is formed in part by such space, but principally by a space that is provided by forming on the exterior of the outer shell, by bending it outward or otherwise, an ofiset or enlargement H. The reason for forming the fiue chiefiy by the offset or enlargement of the outer shell instead of on the innerv shell is that thus any diminution of the fuel capacityof the inner shell is avoided, and of course it is desirable to have such capacity as great as possible. In order to direct air blown into the stove by the bellows upward through the flue G, the inner shell has near its bottom an upwardly and in- Wardly inclined portion (Z', the air on entering the stove that is intended for passage through the fiue G striking such portion and being` directed upward thereby. Beginning at a point about mid-height of the upper shell and thence upward, holes or perforations (Z2 are provided to permit air from the fiue in small quantities to pass into the fire-box.

The smoker shown in Fig. 1 is intended to be loaded from the top, and, as is customary the cover for the top, to which the nozzle or snout is attached, is hinged or pivoted, so that it may be readily opened and closed.

In the use of the smoker illustrated in Figs. 1 and 2 the fuel is placed in it from the top and ig'nited and the top closed. The bellows being operated, some of the air forced thereby into the stove will pass beneath the grate and thence up through the body of the fuel, and a relatively tsmaller quantity of air will IOO IIO

.dense volume of smoke.

pass into and through the longitudinal flue G and out of the latter at the top of the stove and thence directly across the upper end of the stove, having an exit through the nozzle or snout and forcing the smoke through the latter, the air` in its passage across the top of the stove drawing the smoke from the burning fuel upward therefrom and carrying it out through the nozzle in great volume. The air that passes from the fiue G through the small openings (ZZ supports combustion, and air passes therethrough into the fuel-chamber from one hole after another as the level of the burning` fuel descends, and thus uncovers such openings in succession. The air which passes fronrbeneath the grate accelerates the burning of the fuel and produces a Owing to the impediment which the fuel naturally offers to the passage of the air, the blast throug'h the fuel is retarded. I therefore provide the 'tlue G, through which the air passes in an unobstructed course, the result being that the great volume of smoke which is produced is blown from the smoker with great force, and of course the blast that comes from the fiue G is a cool one. As the air enierges from the fine G at a point in line with and diametrically opposite the nozzle or snout there will be a direct blast of air without any eddying or countercurrents, and hence the smoke emerges in a strong and steady stream. It will be seen that by reason of the employment of an inner shell for the fire-box the outer shell of the stove will be prevented from being heated, and thus its life will be greatly prolonged, since where it is excessively heated, as is the case when no inner shell is used, it is soon burned out, and of course as the outer shell is not excessively heated the discomfort of handling a smoker with a highly-heated shell is obviated. Of course the circulation of a volume of unheated air between the two shells is of material benefit in preventing the heating of the outer shell, and as the flne G is situated on that part of the stove which is nearest the bellows, which is grasped by the hands, the presence of such flue at this point contributes to the comfortable handling of the smoker.

The construction of smoker illustrated in Figs. 3 and 4 is similar to that shown in Figs. 1 and 2, except that no grate is employed; but the inner shell rests directly upon the bottom of the stove, and the entire volume of air sent into the stove by the bellows enters the flue G, which is formed precisely like the fine G in the construction illustrated in Figs. 1 and 2.

'Viththe smoker illustrated in Figs. 3 and 4 the combustion of the fuel proceeds from the top downward, and to support combustion a series of holes like the holes CZ in the construction shown in Figs. 1 and 2 open from the fiue into the fire-boX, the air entering the fire-box at a point successively lower and lower as combustion proceeds and the level of the fuel is lowered. There is also the difference in the construction shown in Figs. 1 and 3 thatl air for the annular space between the two shells is supplied through small opening a' near the bottom of the outer shell that communicate with the spaces that lie between the ribs or corrugations (Z, these holes, however, not being provided where any air intro- ``duced into the flue G can escape from the latter, it being desired that all air from the bellows shall be forced through said tluc G.

The construction of smoher illustrated in Figs. 5 and 6 is of the kind known as the breech-loader, the bottom of the stove being removable instead of the top 'for leading. The inner shell D (shown in Figs. 5 and 6) is fastened to and is removable with the bottom of the stove. As in the case of the smoker illustrated in Figs. 3 and et, the combustion proceeds wholly from the top downward, and the air for si1.1')poi'ting combustion and blowing out the smoke is introduced into the fire-box through holes d, arranged in Vertical lines in the wall of the inner shell, the air being supplied to such holes through a fiue G, formed on the exterior of the outer shell, as in the cases of the other two forms of smoker hereinbefore described. Preferably the holes (Z2 are arranged in two sets or series out of alinement with each other vertically, one set extending from the top half-way down the inner shell and the other set extending from half-way down the inner' shell to the bottom thereof, the two sets being adapted one at a time to be placed in alinement and communication with the fiue G by turning the inner shell. 7ith the upper set in alinement with the line G combustion will proceed until the lowermost hole of the set is reached, and in order to Continue the combustion it is necessary to shift the position of the inner shell to bring the lower set of holes into alinement with the flne G. The tube F, which receives the air from the nozzle of the bellows, is somewhat diii'erently constructed from the tube for the same purpose shown in Figs. 1 and 3, said tube F in the construction shown in Fig. 5 having its inner end curved or turned upward, so as to direct the blast of air up into the fiue G. Should it be desired, the flue G instead of being on the exterior of the stove, as shown in Figs. 5 and 6, can be on the inside of the inner shell, and the two sets of holes cl can be formed in the inner sides of the fine-wall, said fine being divided by a Vertical partition (1, one set of holes being on one side of said partition and the other being' on the other side thereof, and the two passages through the fiue thus formed being alternately placed in alinement with the airsupplying tube F according as one set of holes (lg or the other is to be used.

As the inner shell is removable from the IOO stove, it will be seen that whenever necessary a new inner Shell can be supplied, so that as only the inner Shell will be injured or rendered useless from the use of the smoker it is necessary to replace it only` So that the life of the smoker as a whole is Substantially prolong'ed as compared with a construction which is such that the outer Shell is Subjected to eX- cessive heating', and thereby destroyed.

Heretofore the hooks for hanging smokers when not in use have been applied to the bellows. I attach the hanger-hook H to the stove and can do so because the outer Shell of the latter is not hig'hly heated. The placing of the hanger-hook on the stove is important where it is desirable to hang the smoker on the hive, for the escaping smoke will fiow across the open hive and will neutralize the scent of the honey, which attracts robbers, and with the hanger on the stove the smoker is in position for instant use, it not being necessary to turn it around, as is the case when the hanger is applied to the bellows. As a precaution to prevent burning of the hive a Shield consisting of a plate I, of metal or other appropriate material, may be Suspended from the hanger`l So as to be interposed between the stove and the hive. The location of the hanger-hook on the stove is not only a more convenient location for the reasons stated, but it is better than having it on the bellows, for as the greater weight of the smoker is in the stove the hanger-hook is nearer the center of gravity of the smoker.

The perforations through the inner' shell are preferably made sufficientl y small in diameter to prevent the passage of Sparks through them.

It is to be understood that details of construction which have been described with particularity herein are not essential; but the construction may be varied in these particulars without departure from the scope of the invention.

Having thus described my invention, what I claim is- 1. A bee-Smoker, comprising a stove having' inner and outer shells, a fiue in communication with the interior of the stove, space to form the fiue being' provided by an extension or ofiset on the exterior of the outer Shell, and means for introducing' air under pressure to Said fiue.

In a bee-smolier, the combination with a stove 'comprising inner and outer shells, a grate on which the inner Shell rests, a fiue in communication with the interior of the stove, and an air-inlet that is situated So that a portion of the air passing through it goes beneath the grate and a portion enters the fiue at a point above the grate. z

In a bee-smoker, the combination of a stove consisting of inner and outer shells, ribs Separating the shells to form an air-space, a fiue on the side of the outer Shell opposite a space between two of the ribs, said fiue being in communication with the interior of the stove an air-inlet communicating' with the lower end of the fiue, the inner Shell being provided with an air-guiding 'sur-face opposite the air-inlet, and means for forcing air under pressure into the fiue.

8. A bee-smoker, comprising a stove having at'its top a'laterally-extending smoke-outlet, and a bellows attached to the stove at one side thereof, and a hool attached to the opposite Side of the stove below Said smoke-outlet and adapted to hang on the hive.
